In these drawings I- have illustrated one embodiment of my invention andhave shown the same in connection with a liquid dispensing apparatus ofa well known type. It will be understood, however, that this particularembodiment has been chosen for the purpose of illustration only and themechanism may take various forms and may be used in connection withdispensing apparatus of various kinds.

The dispensing apparatus here illustrated comprisesa vertical standardor housing 1 at -the upper end of which are mounted two measuringreceptacles, 2 and 3, which are here shown in the form of glasscylinders of identical size, each hav-- ing a capacity of one gallon, orothersuitable measuring unit. vEach receptacle has at its upper end a;vent 4, the vents of the two receptacles being connected by a pipe 5.Each ventis con- 0 trolled by a valve 6 which is connected with a float7 so arranged that when the receptacle is filled the float will closethe valve. Mounted in the lower portion of the standard or housing 1 isa pump 8 which may be operated in any suitable manner. In the presentinstance it is motor driven and is connected by a pitman 9 with anelectric motor 10, through suitable reducing gearing contained withinthe casing 11. The inlet of the pump is connected by a pipe 12 with asuitable source of liquid supply, such as an underground reservoir, andthe outlet of the pump is connected by a pipe 12a with an inlet pipe 13formed in the casing 14 constituting the upper part of the standard andon which the twin receptacles 2 and 3 are mounted. This inlet conduit 13is provided with branches 15 and 16 leading respectively to valvechambers 17 and 18 whichare connected with the respective measuringreceptacles by passageways 19 and 20.. Thyalvechambers 11 0arealsoconnectedattheirinnerendswith'any outlet conduit 21 the outer endof which is connected with a discharge pipe 22. Mounted in each valvechamber is a piston valve, 23 and 24, the two valves being rigidlyconnected by a rod 25; so that they will move in unison and being soarranged that when moved tothe limit of their movement in one directionthe measuring receptacle 2 will be connected with the discharge pipe andthe measuring receptacle 3 will be connected with theinlet or supplypipe. When the valves are shifted to the other limit of their movementthe measuring receptacle 2 will be connected with the inlet or supplypipe and the measuring receptacle 3 will be connected with thedischarge. pipe. Arranged between the two passageways l9 and 20 is acylinder 26 having mounted therein a double ended piston 27'the'ends ofwhich are exposed to the liquid in the respective passageways. When thatreceptacle which is connected with the supply pipe is filled thecontinued operation of the pump will subject the liquid to pressuresuflicient to shift the piston 2'7 lengthwise ofthe cylinder 26.Connected with the piston 27 is a crank arm 28 rigidly secured to ashaft 29 which extends through the outer wall of the casing 14 and isconnected with the valves 23 and 24 in such a manner 'as to shift thosevalves. As here shown, an arm 30 is secured to the outer end of theshaft 29 and is connected with a second arm 31 which is connected withan arm 31a rigidly secured to a-shaft '32 also extending through thewall of the casing and having secured to its inner end an arm 33 whichis connected with the valve rod 25. The arms 30 and 31 constitute ineffect a toggle and the arm 31 is longitudinally movable in a part 34which is connected with the arm 31a and is acted upon by a spring 35,the arrangement being such that when the two arms are brought intolongitudinal alinement the spring will be compressed and when the armsare moved beyond their alined positions the spring will expand tocomplete the movement of the arms, thus completely shifting the valves.One end of a toggle 36 is rigidly secured to the shaft 29 and the otherend thereof is 'pivotally connected with one arm of the bell crank 37,the other arm of which is connected with a rod 38 which functions in amanner to pensing apparatus forms no part of the present inventionexcept in so far as it enters into combination with the-recordingmechanism and the. controlling devices therefor, and therefore it neednot be described in detail. A full description of a dispensing apparatusof this type will be found in Patent No 1,612,488, granted December 28,1926 to carbanaro.

Associated with the liquid delivery mechanism is a register adapted torecord certain items relating to the liquid delivered, such as ,thenumber of gallons, or other units, delivered-on each Y deliverytransaction and the money value thereof. Preferably the register is ofthe recording type and is provided with means'for printing a record ofthe registered items and for issuing a ticketonwhichsaiditemsareprinted.There'g type wheel is a gear 41 which forms pisteritselfisnotapartofthepresentinvention and I have illustrated onlysuchparts thereof as are n to an understanding of the operation of theinvention. The registering mechanism here illustrated comprises a seriesof type wheels 39 (Figs. 1, 3 and 10) rotatably mounted on thecountershaft'm and connected th each of the mechanism for operating thattype wheel. The printing m comprises two platens, 42

and 43, here shown as rollers carried by a pivoted frame-44 and soarranged that when the frame is moved in one direction from its normalposition the platen 42 will be brought intoprint- .ing relation to thetype wheels and when the frame is moved in .the other direction from itsnormal position the platen 43 will be brought into printing relation tothe type Wheels. Separate webs of paper extend about the respectiveplatens and each web is so supported by its platen that it will be movedinto contact with the type which are in printing position when thatplaten is moved into printing relation to the type wheels.- One of saidwebs becomes a permanent record which is retained in the machine and therecord printed on the other web isdetached and issued as a ticket, as iscustomary in ticket issuing machines. The platen frame 44 is connectedby a pitman 45 (Fig. 7) with. a wrist pin 46 carried by a mutilated gear47 to which is rigidly connected agear 48. The "gear 48 meshes with a orrecord on the'register preparatory to printing the same is controlled bya movable part of the delivery mechanism in such a manner as to cause apredetermined operation of said means upon the delivery of each unit ofliquid. The setting up means for the register may be, connectedtherewith, to transmit the record thereto, in any suitable manner. Inthe present mechanism the set-: ting up means comprises mechanism.constituting an accumulator which is disconnected from the registerduring the delivery of the liquid and after the delivery has beencompleted is connected with the register and actuated to transfer the'accumulated record 3 thereto. The setting up -2- means as a wholecomprises a plurality of sepa; rate devices, there being preferably aseparate setting up device for each counter-wheel 39 of the register.Each of these devices includes an accumulating element which mayconveniently be in the form of a gear. Connected with each suchaccumulator gear are various other elements for controlling theoperation thereof, each group of elements constituting a gear unit. Forthe purposes of the present machine I have provided, as shown in Figs.11, 12 and 13, the two gear units 62 and 63 for the gallonscounterwheel, and four gear units, 68; 69, I0 and '11, for the mills,cents, tens of cents and dollar counterwheel.

The several gear units are similar in character. 5-"

Some of them differ slightly in detail from the others. In Fig. 3 I haveillustrated the cents gear unit-89, which is typical of the other units.except for minor differences which will hereinamr appear. The gear unitthere illustrated :50

comprises a rotatable member52, here shown as a forty tooth gear, (-seeFig. 3), to which a pre-, determined movement is imparted upon thedelivery of each unit of liquid by the dispensing apparatus. The, devicefor imparting this movement to the rotatable member mayconveniently takethe form of a pawl, as shown at 53, and, in the present arrangement, aratchet wheel 54 is rigidly secured to the rotatable member and arrangedto be' engaged by the pawl. The gear 52 and the ratchet wheel 54 arerotatably mounted upon a'normally stationary shaft 55 and the pawl 53 issupported by a suitable pawl carrier here shown as an arm 56 pivotallymounted on the shaft 55 and having an offset portion provided with aradial slot 57. A spring 58 acts on the pawl to press the same towardthe ratchet'wheel. A lever 59-is pivotally mounted at one end on ashaft60 and has at its other end a pin 61 extending into the slot 57 of thepawl carrier so that the movement of the. lever 59 about its axis willmove the pawl carrier about the axis of the shaft 55 and cause the pawlto operatively engage the ratchet wheel. The ratchet wheel is heldagainst reverse movement by a detent pawl 253 which is actuated by aspring 254 rigidly connected with the gear 52 and ratchet wheel 54 is afour tooth gear 64 (Fig. 6.), which actuates ther transfer mechanism, aswill be hereinafter described.

The number of "counterwheels or accumulators 52 will be determined, inpart at least, by the'numher and character of the items which are to beregistered. In the present machine I have shown means for registeringgallons, or units of delivery up to ninety-nine and means forregistering money value of the liquid delivered up to nine dollars and.ninety-nine cents. In some localities the price of gasoline is quoted infractions of a cent, usually in tenths. In order to compute the pricewhere a fraction is involved I have provided a gearunit for registeringin tenths of a cent or mills, such a gear unit being shown at 68 (Figs.11 and 12), \and comprising a four tooth transfer gear 64a and a fortytooth ratchet wheel 54a. As will hereinafter appear the record is nottrans ferred to the register in mills and therefore this gear unit doesnot require the forty tooth counter gear. The cents gear unit, as abovedescribed, is shown at 69, and the tens of cents gear unit is shown at70, the latter comprising a forty tooth gear 52b, a forty tooth ratchetwheel 54b and a four-tooth gear 64b. The dollars gear unit is shown at71 and comprises a forty tooth gear 520 and a four tooth gear 640 and aforty tooth ratchet wheel 540, which, in this instance serves merely tohold the gear unit against reverse movement. The mills, cents and tensof cents gear units are independently actuated by pawls 53a, 53, and53b, (Fig. 10), and levers 59a, 59 and 59b, (Fig. ll), and the amount istransferred from each gear unit of a lower denomination to the gear unitof the next higher denomination by means of transfer wheels 65a, 65 and65b, mounted on shaft 66 and arranged to be engaged respectively by thefour tooth gearsof the three units, and each having connected therewitha transfer gear 67a, 67 and 671), which meshes with the forty tooth gearof the gear unit of next higher denomination. As will'hereinafter appearthe several gear units for computing money values are actuatedsuccessively so that the count may be transferred gear 64d in the gearunit 62.

The count on the mills gear unit 68 is transferred to the cents gearunit 69 upon the first operation of the mills gear unit, that is, whenone mill is registered on the'mills of the gear unit ten mills aretransferred to the cents gear unit. Thus the cents gear unit includes atall times, as

a full cent, any fraction of a cent on the mills gear unit. This ispreferably accomplished by so locating the teeth of the four tooth gearof the mills gear unit that the first movement thereof, from its initialposition, will cause the cents gear unit to be advanced one space ortooth. This arrangement is shown in Fig. 16 'where the teeth four toothgear 64b of the cents gear unit 69 are in the 9 "position.

For the purpose of setting up the number of gallons two accumulator gearunitsare provided "which is actuated by pawl 53d and lever 59d in themanner above described. The gear unit 63 comprises a forty tooth'gear52c, a four tooth gear 64c and a ratchet wheel 64b. This gear unit beingthe tens counter is not operated independently of the unit counter butthe count is transferred thereto by means of the four tooth This fourtooth gear is arranged to actuate a transfer gear 65d which is rotatablymounted on the transverse shaft 66 and has connected therewith a gear67d also. loosely mounted on the shaft 66 and meshing with the gear 52cof the gear unit- 63. The transverse gears 65d and 67d have the same'number of teeth, in the present instance 20, and it will be apparentthat upon each quarter rotation of the forty tooth gear 52d of the gearunit 62 the gear unit 63 will be advanced one step or tooth.

A suitable actuating device is provided for impartingmovement to thepawl actuating levers 59a, 59 and 59b and 59d, and, as here shown, thatdevice comprises a shaft 268 extending parallel withthe shaft .55 whichsupports the gear units and having rigidly secured thereto a series ofarms 269a, 269. 26% and 26907.. each having a laterally extending studor roller 270. and the several arms being spaced lengthwise of the shaft268 to position the same adjacent to the respective pawlactuating'levers 59a. 59, 59b and 59d. Each of these levers is providedwith a downwardly extending projection 271 arranged to be engaged bythe, stud 270 of the corresponding actuating arm, the rear edge of theprojection being inclined so that the stud will act thereon with a camaction and the length of the projection being such that the movement ofthe lever will impart the'desired movement to the gear operating pawl.In the case of the money value computing gear units the pawl has amovement through an. arc of ninety degrees so that the ,gear unit iscorrespondingly short, as shown in dotted lines in Fig. 3. The actuatingarms for the money value computing gear units are spaced about the axisof the actuating shaft 268 so of the four tooth gear 64a of the millsgear unit 7 68 are in the 1 position while the teeth of the that theseveral gear units will be actuatedsuccessively.

Means are provided for causing one complete rotation to be imparted tothe actuating shaft 5 268 upon the deliveryof each unitof liquid andthis complete rotation of the actuating device will cause the pawls foreach of the money value. gear units 68, 69 and IO to be moved through anarc of ninety degrees and will cause the pawl 53d 1 for the gallonscomputing gear unit 62 to be moved a distance of one tooth. 'Inasmuch asthe pawls for the money value gear units move'a uniform distance uponeach operation thereof it is necessary to provide some means for socon-- trolling the operation of those pawls that their gear units willbe advanced distances corresponding to the price per unit of the liquidso that each operation of the actuating mechanism will add the price ofone unit to the gear units and eventuallyto the register. This pricesetting mechanism may take variousforms and,

in the present instance, I have mounted on the shaft 55, adjacent toeach of the gear units 68,

69 and 70, a disk or plate, 72a, 72 and 72b, (see 2 Fig. 5)., whichplates are adjustable'about the axis of the shaft. Each plate hasperipheral portions of different radial width, as shown at 73 and 74.That portion having the greater radial width, '13, has its edge evenwith or slightly be- 3 yond the ends of the teeth of the adjacentratchet wheel 54 and the nose of the pawl 53 is of sumcient width tooverlap both the'plate and'the ratchet wheel and consequently when thiswider portion of the plate is in line with the pawl the 5 latter will beheld out of engagement with the ratchet teeth. That portion of the platehaving the shorter radial width has its edge adjacent to the inner endsof the ratchet teeth so that it will not interfere with the engagementwith the teeth 40 by the pawl. The plate may be adjusted about the axisof the shaft in any suitable manner but, as here shown, it has a thirdperipheral portion provided with gear teeth, as shown at '15, and theseteeth mesh with a pinion 76 (Fig. 3) rotatably mountedon a shaft '77 sothat by actuating the several pinions 76 the pawl controlling plates forthe respective gear units may be adjusted to the desired positions. Inthe present machine the pinions '76 are arranged to be engaged andactuated by the finger of the operator, itbeing understood that theplates are adjusted only when the price per gallon changes. Preferablyeach pinion '76 has secured thereto an indicator '78 (Fig. 11) whichwill indicate to the operator the position of the plate. Detents 79normally engage the teeth of the price setting pinions '16 to hold thesame, and consequently the plates, against displacement. It will beapparent, therefore, that by releasing the detent and adjusting theplates 72a, 72 and 72b of the respective gear units to selectedpositionswith relation to the ratchet wheels of those units themechanism may be caused to register. any desired price per unitof liquidon each operation thereof. For ex- .ample, if the price of gasoline is18 %.cents per gallon the plate 72a of themills gear unit would be @setto cover all but three of the ratchet teeth which are positioned withinthe limits of'travel of the pawl 53a, the plate 72 for the cents counterwould be set to cover two of the ratchet teeth which arepositioned-within the limits of travel. 32 the pawl 53 and the plate 72bfor the tens of cents counter would be set to cover all but P one oftheratchet teeth which are positioned within the limits of travelof thepawl 53b.

The two gears maybeconnectedonetotheothertocausethemto rotate in unison, and thuscausepower to be means of a pinion 88 which is of suflicient width tomesh with the teeth of both gears 86 and 87 and is movable into and outof mesh with thew gears. As here shown, the pinion 88 is carried by anarm 89 pivotally mounted on the shaft and is moved into and outof..oper'ative engagement with the gears 86 and 8'1 by a mechanism whichwill be hereinafter described. Sufice it to say here that this mechanismis of such a character that during the delivery of the liquid theactuator shaft is connected with the motor. It may also be noted herethat when the actuating de-' vice is disconnected from the motor thelatter is connected with the printing mechanism. To this end the gear51which actuates the platens 42 and 43 meshes with a gear 90 looselymounted on a shaft 91. Loosely mounted on the shaft 91 alongside thegear 90 is a second gear 92 which meshes withthe driven gear 85. Thegears 90 and92aresoarrangedthatwhentheconnecting pinion 88 is moved outof mesh with the gears 86 and 87 on the actuator shaft it will be movedinto mesh with the gears 90 and 92 for the printing mechanisms Thecircuit for the otor 81 is controlled by a switch, which as shown inFig. 8, comprises a stationary contact member 93 and a movable contactmember 94, the latter being provided with an extension or finger 95 bymeans of which it may be actuated. Aswitchactuating lever 96 13c ispivotally mounted on a fixed axis, as shown at 9'1, and has at one end atransverse projection 98 which extends beneath the finger, or extension95 of the movable switch member and serves to control the position ofthat switch member. A spring 99actsonthelever96tomovethesameinadirection which will cause the switch tobe closed. Normally this movement of the lever is prevented by a latch100 having ashoulder 101 which engages beneath the transverse projection98 on the lever, when the latter is in its elevated position, andretains the switch in its open position. A-

spring 10': holds the latch normally in operative engagement with thelever. A finger 103 on the m5 latch extends into the path of a ing orprojection 104 carried by a vertically reciprocatory switch.operatingmembe'r 105 which is provided with'slots106bymeansofwhichitisslidablymmmted on studs 107. 'ihe switchoperating membenlo5 150.v

is held normally in its elevated position by a spring 108 which isconnected at one end with the upper stud 107 and at its other end with astud 109 on the switch operating member. When the operating member ispressed downwardly the lug 104 thereon will actuate the latch againstthe action of the spring 102 to release the lever 96 and the spring 99will move that lever about its axis and therebyrelease the switch 95 andpermit the latter to close, this being accomplished by the resiliency ofthe support for the movable contact member. Mounted on the shaft 84 is acam 110 having a projecting portion or lobe 1 11. The lever 95 has atthat end thereof, opposite the projection 98, an upwardly extending nose112 which is so arranged'with relation to the cam 110 that when theparts are in their normal positions, with the switch open, the nose willlie just behind the canf projection 111 and will be spaced radiallybeyond the same. When the switch operating member 105 is depressed andthe lever 96 released the nose 112 of that lever will move inwardly intocontact with the periphery of the cam 110 in the rear of the projection111. The switch having been closed the motor will operate on the shaft84 and the cam 110 will rotate in the direction of the arrow and as theshaft completes a single rotation the projecting portion 111 of the camwill force the nose 112 of the lever 96 outwardly thus moving thetransverse projection 98 at the opposite end of the lever upwardly toopen the switch and to permit the latch 100 to again engage the securedto the lever 96 at the axis thereof is an arm 115 having a nose 116 sopositioned that when the parts are in their normal positions, with theswitch open, the nose 116 will extend into the recess '114 and will forma stop to prevent the.

rotation of the disk and consequently of the shaft. When the switchcontrolling lever 96 is released and moves in a direction to close theswitch the nose 116 of the arm 115 will move out of the recess in thedisk and the latter will be free to rotate but when the cam actuates thelever 96 to restore the parts to their normal position the nose 116 willbe again moved into the recess 115 and will stop the movement of thedisk at the end of a complete rotation. However, it is not practical toinstantly stop an electric motor and I have therefore interposed a slipconnection between the motor and the shaft 84. As shown in Fig. 11, theworm gear 83 is carried by a sleeve 117 in which the shaft 84 isrotatably mounted and the end of this sleeve is provided with anenlargement or disk 118 adjacent to the disk 113, which is rigidlysecured to the shaft 84 and friction material 119 is interposed betweenthe disks under sufficient pressure to cause the two parts to normallyrotate in unisonbut to permit the sleeve to rotate with rel cnto theshaft when the movement of the latter is suddenly checked.

The switch operating member 105* is actuated by a movable element of ihedispensing appathe switch operating member is' provided at its upper endwith a lateral extension or head 120 which, as above described, isactuated-by the shaft 29 of the delivery mechanism upon each operationthereof. Consequently each time the valve mechanism of the dispensingapparatus is reversed the finger 128 will, through the connectingmechanism, depress the switch operating member 105 and cause the motorto impart one complete rotation to the actuating device;

As has been stated, the count which is received by the gear units may betransferred to the registering device in any suitable manner and at anysuitable period during the operation of the mechanism but, in thepresent device, the gear units serve as accumulators and the accumulatedcount, or tctalized record, is not transferred until the end of thedelivery operation. Consequently the gear units are normallydisconnected from the register and a connection must be establishedbefore the count can be transferred. In the present mechanism I haveutilized the transfer pinions 67a, 67, 67b and 67d as parts of the meansfor connecting the gear units or accumulators with the register. Thesetransfer pinions are in constant mesh with the forty tooth gears of therespective gear units and I have mounted adjacent to each of thesetransfer pinions, which are here shown as twenty-tooth gears, idlepinions 131a, 131, 1312) and 131d, (Figs. 3 and 13) which mesh inintermediate gears 132 which in turn mesh with the respective gears 41which are connected with the type wheels of the register.

Inasmuch as the gear unit 62 was driven by the actuating pawl toregister units of gallons it has no transfer gear in mesh with the gear52d and I have mounted on the shaft 66 an idle pinion 290, which is inmesh with the gear 52d and an idle pinion 291, which is in mesh with thecorresponding intermediate gear 132. (Figs. 12

and 13.) The pinions 67a, 67, 67b, 67d and 290 are normally disconnectedfrom the pinions 131a, 131, 131?), 131d and 291 so that the operation ofthe first mentioned pinions, during the delivery of liquid, does notaffect the last mentioned pinions or the register. When the gear unitsare to be connected with the register the pinions 133, 133a, 133b, 1330and 133d aremoved into mesh with the respective pairs of pinions on theshaft 66, each pinion, 133, 1330., 133b, 1330 and 133d being wide enoughto mesh with both of the other pinions, thereby causing those pinions torotate in unison and causing any movement of the forty-tooth gears to betransmitted to the corresponding type wheels of the register.

As here shown, the pinions 133, 133a, 1331;, 1330 and 133d are mountedon a shaft 292 carried by arms 134 rigidly mounted on the shaft '77.Rigidly secured to the shaft 77 is an arm135 extending to a pointadjacent to the shaft 55 and having at its end a stud 136 extending intoa cam groove 137 of a cam 138 (Fig. 7) which is rigidly secured to theshaft 55. The shaft 55 is provided with suitable means, such as a crank139,,for operating the same and the arrangement of the cam 138 withwhich a s a stud'or r0l1ei' 121 (Fig. 7) is such that the first movementimparted to the pinions 133, 133a, 1332), 1330 and 133d into mesh withthe corresponding-transfer pinicns andthereby establish the connectionbetween the gear units or accumulators and 'the register. The cam grooveis so shaped that the pinion will be held in this position untilthe-shaft operating device has completed its movement and been returnedto its initial position. Means are also provided to cause the first partof the movement of the shaft 55 to shift the pinion 88 and therebydisconnect the actuating device from'the motor and connect the latterwith the printer. For this purpose an arm 140 is rigidly connected withthe arm 89 which carries the pinion 88 and has at its free end a stud141which travels in a box cam 142, the cam groove being so shaped that thefirst movement of the cam will shift the pinion and during the remainderof the movement of the cam the pinion will be held in the position towhich it has been moved, that is, in a position toconnect the motor withthe printer. The type wheels 39 of the register may be reset in anysuitable manner. In the present machine they are reset'by restoringtheintermediate -gears 132 to their initial positions, and this isaccomplished automatically at the end of each printing operation. Forthis purpose a yoke 190 (Fig. 3) is pivotally mounted on the axis of the.gears 132 and extends across the peripheries of those gears in thepaths .of fingers 191 carried by the respective: gears. The yoke ismoved in a reverse or resetting direction by a spring 192. When thegears'132 are actuated-to transfer the count to the type wheels the yokewill be moved against the action of the spring a distance equal to thegreatest distance traveled by any of the gears and when the connectingpinions 133 are withdrawn and the gears 132 released the yoke will bemovedin a reverse direction by the spring and will pickup the fingers191 of the several gears ahd carry the gears to their initial positions,thus also returning the typewheels to their initial positions. 'A stop193 is provided to check the movement of the gears 'when' they havereached. their initial positions.

It is desirable that the liquid dispensinga'pparatusshouldbe renderedinoperative during the er of the record and it is preferable that thisshould be accomplished at the beginning of thetransfer operation. I havetherefore provided m'eans wherebythe circuit through the pump operatingmotor will be broken during the initial movement of the shaft operatingdevice 139.- As shown in Fig. 7, the pump motor switch comprises a fixedcontact 143 and a movable contact 144 carried by a resilient arm 145. Acrank arm 1461s mounted'on a fixed axis 146a adjacent to the resilientarm 145 near itsfree end a stud 147 on which is mounted. a roller 148,preferably of insulating material, which contacts with the resilient arm145. Rigidly connected with the arm 140, which actuates the pinion 88,is an arm' 149 having its free end, in-

clined, as shown at 150, and arranged in contact -withthe stud 147 onthe arm'l48, the arrangement. being such that when the "arm 140 isactuatedby the cam 142 the inclined ehd of the 7 arm 149 will act'onthcstud14'l and cause the,

roller 148 to'press the movable contact member 144 out of engagementwith a fixed contact mem her 143 thus breaking the circuitthrough thepump motor. The arm 149 is retained in a position to maintain thecircuit broken lmtil the o'persting device is returned to its i1,955,004 shaft by its operating device will move the At the end of eachdelivery transaction the gearunitsareresettosermtherebeingofcourse fourzero positions on each forty-tooth gear, and this resetting movement ofthe gears is utilized to transfer'the count to the register through theconnection which has been established. In the present instance, the gearunits are reset by continuing their movement in the normal direcrtion ofoperation, thus causing each forty-tooth gear, when reset, to be movedto a distance equal to the difference between the amount registeredthereon and ten. The type wheels of the register are set normally intheir zero positions and the connections between the same and the gearunitsaresuchthatwhenthe gearunits are ad-' vanced to complete themovement thereof, and thus reset, the respective typewheels will berotatedinareversedirectiondistancesequaltothe distances to which thecorresponding gear units are moved. For example, if one of the gearunits has accumulated a count of eight it will be moved forwardly adistance'of two-teeth in resetting'the same, and this movement whentransmitted through the connecting gearing to the,

corresponding type wheel will move that type' wheel in a reversedirection the distance of two teeth, thus'bringing the "8" type intoprinting position. The four tooth gears 64a, 64,.64b, 64c, 54d and 64ewhich form parts of the mechanism for transferringthe count from onegear unit to mother also constitute parts of the re setting mechanismand all the gearunits are therefore provided with these four toothgears. Cooperating with each four tooth gear is a pawl 151,- the severalpawls being in the present instance formed from one piece of metal andbeing moimted on a rod 152 carried by arms 153 .pivotally moimted on theshaft 55. Means are provided whereby each complete operation of theoperating devieel39 for the shaft 55 will move the pawlfi 151 through anarc of ninety degrees. The for actuating the pawls 151.shouldbeofsuchacharacterthatthepawlswill not impart movement to thegear units until-the connection has been established between the gearunits and'the register and after the resetting operation has beencompleted the operating device shouldhave a slight'movement, after thepawls are' stopped, for the purpose which will hereinafter appear. Thismay be accomplished in various ways and'in'FlgfB. I have shown onebymeansofwhichthedesired results'msybesecurcd. Asthere shown,'anarm154isrigidlysecuredtotheshaft 55and asec- 0nd arm 155 is loosely'mountedon-that shaft. A spring 156 is connected at one end with a pin.15'lontheann154andattheotherendwitha of one of-the arms153 but isnormally spaced some distance therefrom. When movement isimpartedtotheshaft55thit 154willrotate with the shaft and cause the arm155-to move therewith but-the distance between the pin 158 and the edgeof the pawlcarrying arm 1531s such that the cams 138 and 143 willhaveample time tofunctionbefore movement isimpartedto'the pawl carryingarms. After the a.rm 1." 5- has .willbemovedthroughanarcofnmetydegrefi,

andduringthis t theywill pick up the next preceding teeth on thefourtooth gearsand thereby move each gear unit to itlaerogpositioml pawlsupporting armldtengaga'the picked up the pawl carrying arm-153 thepawls' stop 159 the shaft 55 and arm 154 may continue to move in thesame direction due to the yielding of the spring 156, this additionalmovement being suflicient to cause the motor to operate the printingmechanism. This lattercperation is brought about by means of an arm 160(Fig. 7) rigidly secured to a shaft 161 and having a pin 162 arranged inthe path of a part or edge 162a of the cam 142'and so arranged that itwill be engaged by that part of the cam just before the cam completesits movement. Rigidly connected with the shaft 161 is a slotted arm 163which engages a pin 164 on the link 125 forming part of the switchoperating mechanism. Consequently after the count has been transferredfrom the gear units to the register, by the resetting of the gear units,the further movement of the operating device 139 will cause the circuitto be closed through the motor and the record printed.

Inasmuch as the mechanism.must be manually operated to bring about theprinting of the record it is desirable that some means be provided torequire the operator to print the record. 1 o. the present mechanism Ihave provided means whereby the accumulation of a money value of anexcessive'amount on the gear units will cause the circuit through thepump motor to be broken and will prevent the closing of that circuituntil the record has been printed. This, of course, does not force theoperator to print a record of each transaction but he must ultimatelyprint the accumulated record and if the records printed are abnormal aninspector will know at once that each transaction record has not beenprinted. The.

means for accomplishing this comprises an arm 165 rigidly connectedwiththe switch operating mechanism 146 and having a laterally extendingprojection 166 arranged in the path of an arm 167 mounted on the shaft77 and having connected therewith an arm 168 arranged to be actuated bya cam169 rigidly connected with the dollars gear unit. This cam is afour lobe cam and is so arranged with relation to the gear unit thatwhen the dollars gear passes from the eight to the nine position one ofthe lobes of the cam will engage the arm 168 and impart sufiicientmovement thereto to cause the switch to be opened, thus interrupting theoperation of the motor whenever the amount of $9.00 has been accumulatedwithout the record being printed.

Each lobeof the cam has a dwell of suflicient length to hold the switchin its open position until the gear unit has been moved to its open orzero position. Inasmuch as the dispensing mechanism is inoperative theonly way in which the gear unit can be moved to that position is byoperating the resetting mechanism and causing the record to be printed.When the gear unit is reset to.zero the arm 168 will be released and thepump motor switch will close. A full stroke mechanism is provided toprevent the operator from moving the resetting mechanism far enough torelease the arm 168 and then returning the'same to its initial positionwithout closing the switch through themo.or which operates the printingmechanism.

The full stroke mechanism for forcing the operator to complete themovement of the operating device 139 and the shaft 55 in one directionbefore he can reverse that movement may take various forms. As shown inFigs. 11 and 14, I have rigidly connected with the shaft 55, adjacent tothe operating handle 139, two segments 170 and 171 having opposedratchet teeth. Pivotally mounted on a stud 172, mounted on a fixed sup-'end a hook shaped portion 177 adapted to engage over a stud 178 on theadjacent pawl to hold'that pawl in its inoperative position. This frameordinarily swings free on the shaft 55 and one of the segments isprovided with studs 179 and 180 arranged on opposite sides of the frame,so that one or the other of these studs will engage the frame and impartmovement thereto as the operiating device completes its movement in onedirection or the other. The movement of the frame is limited byprojections 181 extending downwardly on the opposite sides of the pawlsupporting stud 172. Each toothed segment is provided with a cam 183,these cams being so located with re- ,iation to the respective segmentsthat as the operating device approaches the limit of its movement one ofthe cams will engage the pawl which is in operative engagement with itssegment and move the same out of engagement therewith. For example, asshown in Fig. 14, the pawl 173 is in engagement with the segment 170 andwhen the operating member 139 is moved to the right and approaches thelimit of its movement in that direction the earn 183 of the segment 170will engage the pawl 173 and force the same out of engagement with thesegment. Immediately following the movement of the pawl to itsinoperative position the stud 180 will engage the swinging frame, 1'76and move the. hook shaped portion 177 thereof above the stud 178 on thepawl, thereby locking this pawl in its inoperative position. .At thesame time the hook shaped portion 177 on the other edge of the swingingframe will be moved out of engagement with thestud 178 on the pawl 174,thereby releasing that 'pawl and permitting it to be moved intoengagement with the toothed segment 171. As the'operating handle ismoved in a reverse direction, that is to the left in Fig. 14, the pawl174 will hold it against reverse movement until the 'cam 183 ofthesegment 171 reverses the pawls in the manner above described.
